Why are elderly individuals at a greater risk for drug interactions?

Elderly individuals are at a greater risk for drug interactions primarily because they often have multiple chronic illnesses. This demographic frequently requires treatment for various health conditions, leading to the prescription of multiple medications, also known as polypharmacy. Each additional medication increases the likelihood of interactions between drugs, which can lead to adverse effects or reduced efficacy of treatment.

The complexity of managing several health issues simultaneously means that healthcare providers must carefully consider the potential interactions between the prescribed medications. Factors such as changes in how the body metabolizes drugs with age, alongside the presence of multiple health conditions, play a significant role in the heightened risk for drug interactions among older adults. This makes awareness and careful management crucial for ensuring safe and effective medication use in this population.
